Time domain resources for transmission can be flexibly set.

In an embodiment of the present invention, one SS Block may include a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH). Broadcast Channel), or may also include time information related to the SS Block. Also, in one SS Block, PSS and SSS are separated in the time domain, and PBCH, PSS and SSS are also separated in the time domain.

In the process of describing specific embodiments, one information-indicated offset amount may be the numerical value of the offset amount directly indicated by this information, or one of a set of scheduled offset amounts directly indicated by this information. It may be an identifier for a certain amount of offset, and the terminal device can determine a specific numerical value for the amount of offset based on this identifier.

Alternatively, in S110, when the time domain location indication information includes the first time domain offset information, the terminal device receives the time domain location indication information and then converts the first time domain offset information and the method defined in the protocol. And/or according to other configurations of the system, specifically determine the location of the time domain resource of each first SS Block. Here, the position of the time domain resource of the SS block group may be the starting position of the time domain resource of the first SS block whose time domain position is the foremost among the M first SS blocks, or the SS block. The position of the time domain resource of the group may be the end position of the time domain resource of the first SS block whose time domain position is the last among the M first SS blocks, or the end position of the time domain resource of the SS block group. The position may also be the start position or the end position of the time domain resource of any one of the M first SS blocks, and this application does not limit it.

For example, as shown in FIG. 2, the network equipment and the terminal device are closely related to the time domain resource locations of SS Block #1, SS Block #2 and SS Block #3, and the SS Block consists of these three SS Blocks. It may be agreed in advance that the position of the time domain resource of the group refers to the middle position of the time domain resource of SS Block #1, and T_W in FIG. 2 indicates the offset amount of the three SS Blocks as a whole from the preset position , the terminal device can determine the time domain resources of each SS Block among the three SS Blocks based on T_W and other information (protocol definitions and/or other configurations of the system). Here, other information may be, for example, the size of the time-domain resource of each SS Block, the resource scheduling period (eg, 10 ms in FIG. 2), and the like.

Optionally, in S110, the time domain location indication information further includes second time domain offset information, the second time domain offset information being the location of the time domain resources of each first SS block relative to the location of the time domain resources of the SS block group. Used to indicate the amount of positional offset.

For example, as shown in FIG. 3, T_W indicates the offset amount of the three SS Blocks as a whole relative to the preset position, T_2 indicates the offset amount of the position of the time domain resource of SS Block #2 with respect to T_W, and T_3 indicates the offset amount of T_W. indicates the amount of offset of the location of the time domain resource of SS Block #3 relative to T_W, T_2 and T_3, and the terminal device determines the location of the time domain resource of SS Block #1, SS Block #2 and SS Block #3 based on T_W, T_2 and T_3. can do. If the protocol stipulates the size of SS Block or the network device informs the terminal device of the size of SS Block through other configuration information, the terminal device will use SS Block#1, SS Block#2 and SS Block#3 time domains. Resources can be further determined.

Alternatively, in S110, the time domain location indication information further includes time domain resource indication information and first quantity information, the time domain resource indication information is used to indicate the target time domain resource, and the target time domain resource is The first quantity information is used to indicate the value of M, including only the time domain resources of the SS block group.

Note that the target time domain resources may only include the time domain resources of the SS block group.

For example, as shown in FIG. 4, T_W1 indicates the offset amount of SS Block#1 and SS Block#2 as a whole relative to the preset position, and T_G1 indicates the time domain resources of SS Block#1 and SS Block#2. After receiving the time domain location indication information sent from the network device, the terminal device can determine the time domain locations of SS Block #1 and SS Block #2 based on T_W1, T_G1 and the first quantity information. If the protocol specifies the size of the SS Block or the network equipment informs the terminal device of the size of the SS Block through other configuration information, the terminal device further determines the time domain resources of SS Block #1 and SS Block #2. be able to.

Alternatively, in S110, the time-domain location indication information further includes time interval information and second quantity information, and the time interval information indicates that the terminal device determines two adjacent first SS blocks among the M first SS blocks. The second quantity information is used to indicate the value of M, which is used to determine the time interval between the locations of the time domain resource.

Specifically, in some embodiments, the time interval information is used to indicate the minimum time interval between the locations of time domain resources of two adjacent first SS blocks. Or, if M is a positive integer greater than or equal to 2, the time interval information is between the end position of the time domain resource of the i-th first SS block and the start position of the time domain resource of the i+1-th first SS block. Used to denote time intervals, i=1, . . . M−1. Or, the time interval information is used to indicate the time interval between the start position of the time domain resource of the i th first SS block and the start position of the time domain resource of the i+1 th first SS block, i=1, . . . M−1.

For example, as shown in FIG. 5, T_W1 indicates the amount of offset of SS Block #1, SS Block #2 and SS Block #3 from the preset position as a whole, and the time between the positions of the time domain resources of adjacent SS Blocks. If the interval is the same and both are T0, after receiving the time domain location indication information, the terminal device determines the time domains of SS Block#1, SS Block#2 and SS Block#3 based on T_W1 and T0. A resource can be located. If the protocol stipulates the size of SS Block or the network device informs the terminal device of the size of SS Block through other configuration information, the terminal device will use SS Block#1, SS Block#2 and SS Block#3 time domains. Resources can be further determined.

In addition, when the terminal device determines the location of the time domain resources of each SS Block based on the time domain location indication information, there are time domain resources that have other uses in the protocol and cannot be used for transmission of the SS Block. In some cases, the terminal equipment needs to determine the location of the time domain resources of each SS Block based on the time domain location indication information and the time domain resources that cannot be used for the transmission of these SS Blocks.

For example, still taking FIG. 5 as an example, the time interval information indicates that the time interval between the time domain resource positions of two adjacent SS Blocks is three Orthogonal Frequency Division Multiplexing (OFDM) symbols. The terminal device indicates that the time domain resource of SS Block #2 is in OFDM symbols numbered #1, #2 and #3 (the OFDM symbol number in one subframe starts from #0), and numbered #7. When determining that the OFDM symbol cannot be used for transmission of the SS Block, the terminal equipment determines that the starting position of the time domain resource of SS Block #3 is the OFDM symbol numbered #8. Therefore, the time interval between the finally determined starting position of the time domain resource of SS Block #3 and the starting position of the time domain resource of SS Block #2 of the terminal device is actually four OFDM symbols.

In all the above embodiments, optionally, the M first SS blocks correspond to the first cell, and when the network equipment determines the location of time domain resources of each first SS block, at least one first SS block time The position of the domain resource and the position of the time domain resource of any one of the N second SS blocks do not overlap or overlap incompletely. Here, the N second SS blocks correspond to second cells, the second cells being adjacent cells of the first cell, and N being a positive integer of 1 or more.

In other words, the time domain resources for transmitting the SS blocks in the first cell determined by the network equipment and the time domain resources for transmitting the SS blocks in the second cell either imperfectly overlap or do not completely overlap. , thereby avoiding interference between synchronization signals in two adjacent cells, and improving the detection performance of the terminal device for detecting synchronization signals.

Optionally, if the cell identifiers (ID, Identification) of the first cell and the second cell are different, the network equipment can determine the location of the time domain resource of each first SS block based on the ID of the first cell.

Moreover, neither the position of the time domain resource of each first SS block nor the position of the time domain resource of each second SS block of the N second SS blocks have overlapping portions. That is, the time domain resources for transmitting the SS blocks of the first cell and the second cell do not completely overlap.

For example, as shown in FIGS. 6 and 7, if two cells assume that there are four SS Blocks to be transmitted, the SS Blocks of the two cells are completely shifted in the time domain, and this Therefore, both the synchronization signal and the signal such as the PBCH may deviate, and the detection performance of the terminal apparatus for the synchronization signal and the PBCH signal is improved.

Or, as shown in FIG. 8, one cell has two SS Blocks to be transmitted, and another cell has four SS Blocks to be transmitted. Block is completely misaligned in the time domain.

Or, assuming that there are two SS Blocks to be transmitted in two cells, the SS Blocks of different cells do not need to be completely shifted in the time domain, and a portion of the signal may be shifted in the time domain. . As shown in FIG. 9, only the PSS is shifted in the time domain to improve the detection performance of the terminal device for the PSS signal. Alternatively, as shown in FIG. 10, the PSS and SSS are shifted in the time domain to improve the detection performance of the terminal device for the synchronization signal.

Note that in the above embodiments, the PSS or SSS may not occupy a complete OFDM symbol, at which time the OFDM symbol may be divided into several sub-symbols, and the PSS or SSS Occupies only part of the sub-symbol.

Optionally, in some specific embodiments, the network equipment can determine the beams in which interference may occur in the first cell and the second cell, and the location of the time domain resources of the SS Block. When determining , the beams that may cause interference may transmit SS Blocks on different time domain resources, and other non-interfering beams may transmit SS Blocks on the same time domain resources.

In an embodiment of the present application, the first cell and the second cell may optionally be cells belonging to the same network equipment, or the first cell and the second cell may be cells belonging to different network equipment. For example, the first cell belongs to the first network device, the second cell belongs to the second network device, and the first network device uses the reference information when determining the location of the time domain resource of each first SS block. receive and determine the location of the time domain resource of each first SS block based on the reference information, where the reference information may be information directly indicating the location of the time domain resource of each second SS block; Alternatively, it may be information that indirectly indicates the position of the time domain resource of each second SS block.

Also, the first network device directly receives the reference information transmitted from the second network device via the interface with the second network device. Alternatively, the first network device receives the reference information sent from other devices in the system, and embodiments herein do not limit this.
